Abstract Nitrification, a key pathway of nitrogen (N) loss from agricultural soils, is performed by ammonia-oxidizing bacteria (AOB) and archaea (AOA). We examined the seasonal dynamics (2 years) of ammonia oxidizer gene abundances across a gradient

Introduction Endocrine therapy (ET), specifically aromatase inhibitors (AIs) that lower estrogen to subphysiologic levels and estrogen receptor (ER) degraders that non-selectively and negatively impact ER function, may induce genitourinary syndrome o

The oxide cathode is probably the most widely used electron emitter in vacuum electronic devices and is still in use today. This paper reviews the evolution of the theories and technology of the oxide cathode from its origins in 1904 up to the presen

At the last international vacuum electron sources conference, held in Saratov, Russia, the current authors presented a paper reporting on preliminary findings from an investigation into the interfacial layer that forms in the oxide cathode over accel

Oxide cathodes act as electron sources in cathode-ray tubes (CRTs). In an attempt to understand the processes leading to degradation in their performance over their lifetimes, SEM, EDX and AES have been used to examine the Ni base/emissive oxide inte

Sufficient oxide cathode life of several years in a cathode ray tube (CRT) environment at increased load is one of the key parameters in advanced CRT development. When changes are introduced, accelerated life tests are needed in order to quantify the

In cathode ray tube (CRT) thermionic oxide cathodes, the nickel-oxide interface properties are key to understanding the mechanisms of operation. At the elevated operational temperatures, free barium is formed at the interface by the reaction of reduc
